Symbols On
Use the Symbols On option to display a symbol beside each sample in a sample group.
You must have a symbol field in your samples database that contains the name of the symbol to be used for each sample. The default name for the symbol field is SYMBOL. However, it may be specified in the DB_FIELDS section of the . smp file as something else. The default symbol angle is " 0.0 ", and the default unit size is " 1.0 ". These can also be read from the database using the fields SYMANG and SYMSIZ respectively. Again, they can be changed in the . smp file.
| Database Fields | |||||||
| Record | Field | Field | Field | Field | Field | Field | Field |
|---|---|---|---|---|---|---|---|
| SAMPLE | ID | X | Y | Z | SYMBOL | SYMSIZ | SYMANG |
To change the last three default names to SYM , SIZE and ANGLE , the DB_FIELDS section in the . smp file should show:
SYMBOL = "SYM"
